iPhone Check Settings for your Model Name Open

Your phone will tell you in about ten seconds. Worth doing — iPhone models look alike, and cases are cut to the millimetre.

01 Open Settings on your iPhone
02 Tap General, then About
03 Read the line marked Model Name — that's what you order

Model Name, not Model Number. The line underneath shows something like MTQE3X/A — that's a manufacturing code and it won't help you choose a case.
Same year doesn't mean same size. An iPhone 17, 17 Pro, 17 Air and 17 Pro Max are four different bodies with four different camera layouts. A case made for one will not fit the others, even though the names look almost identical.
Buying for someone else? If you can't get to their phone, the model is printed on the original box, or on the receipt from their carrier or the Apple Store.
Apple Watch It's engraved on the back of your watch Open

It's engraved on the back of your watch — no measuring required.

01 Take your Apple Watch off your wrist
02 Turn it over and look at the back
03 Find the number followed by mm, engraved near the top

Then choose your band size
38 / 40 / 41 / 42mm
Small case
44 / 45 / 46 / 49mm
Large case

There are only two sizes to choose from. Small covers 38, 40, 41 and 42mm. Large covers 44, 45, 46 and the 49mm Ultra. Every Apple Watch model uses one of these two fittings, so once you've picked the right one, it fits — no compatibility to worry about.

One thing to remember: the number on the back is your case size, not your wrist size.

AirPods Match the model number under the lid Open

Three ways to check, from quickest to most certain. Take a minute — AirPods cases look almost identical from a distance, and the differences that matter are millimetres.

First, the thing most people miss. A protective case fits your charging case, not your earbuds. Two generations can share the same earbuds and still need different covers, because the case changed shape, moved the speaker holes or swapped the charging port. So it's the case you need to identify.
Method 1 — Ask your iPhone

The fastest way, and it names the model in plain English. Your AirPods need to be connected.

01 Put your AirPods in and open Settings
02 Tap your AirPods where they appear near the top of the list
03 Scroll to About and read Model Name

Method 2 — Look under the lid

Open the charging case and turn it so you can see the underside of the lid. There's fine print there, including a model number starting with A. This is the number that decides which cover fits — match it below.

Charging case Model
AirPods (1st gen) A1602
AirPods (2nd gen) A1938
AirPods (3rd gen), Lightning A2897
AirPods (3rd gen), MagSafe A2566
AirPods 4 A3058
AirPods 4 with ANC A3059
AirPods Pro (1st gen) A2190
AirPods Pro 2, Lightning A2700
AirPods Pro 2, USB-C A2968
AirPods Pro 3 A3122

Model numbers as published by Apple. AirPods Max has no charging case, so it isn't listed here.

Method 3 — Look at the earbuds

Not definitive, but it narrows things down fast.

Silicone ear tips — it's a Pro. The tall, narrow case belongs to Pro 1; a wider case with a lanyard loop on the side is Pro 2 or Pro 3.
Long stems, no tips — AirPods 1 or 2, in the tall narrow case.
Short stems, no tips — AirPods 3, 4, or 5 in the wider, squatter case.
Lightning or USB-C matters. AirPods Pro 2 was sold with both. The cases are near-identical to look at, but the port cutout sits differently — check the bottom of your case before you order.
"AirPods 3" and "AirPods Pro" are not the same thing. They came out around the same time and the earbuds look similar in photos, but the cases are different sizes. If yours have silicone tips, you have a Pro.
Serial number won't help you. The long code under the lid is for warranty and support. The number you want is the shorter one starting with A.
